What I can say, the boot time offset randomization should make every running kernel different in the World, of course, until every running kernel has this feature in effect. Further, this should make automated hack attempts a bit harder.
Combined to the above I came to think about this LWN.net article a while back: Persistent storage for a kernel's "dying breath", https://lwn.net/Articles/434821/.
It would be interesting to have a snapshot of the system after an oops caused by kernel memory poking. After a while, an active and automatic detection system could be useful to analyze and put aside the easy oops snapshots. Just wondering, if anybody already does this and this way gathers valuable information?
